7.2.3 Write commands
The interface module recognizes the following write commands, which you
can use to transfer values to the constant temperature equipment.
The constant temperature equipment confirms each write command
with OK, e.g. the reply from the device address A015 is
"A015_OK". In the event of an error, an error message is output
as a reply, e.g. "A015_ERR_6", see
.
